Abstract Scope |
Lattice structures are essential for lightweight and robust components in additive manufacturing (AM). The most common type are uniform lattices, which use a single lattice topology, however other lattice structure types offer more geometric and functional flexibility. For example, graded lattice structures vary density of a lattice throughout the part to achieve unique properties. Multi-lattice structures offer further flexibility, incorporating multiple lattice topologies within a single component. However, diverse lattice types necessitate thorough simulation and testing to achieve design objectives. Many studies experiment on either multi-lattice or graded structures, but do not compare them directly. Our research comprehensively tests uniform, graded, and multi-lattice structures under compression loading to evaluate mechanical behavior. In this work, we compare these structures in compression loading scenarios, examining key mechanical parameters such as stiffness, strength, and deformation characteristics. Our findings provide valuable insights into the mechanical behavior of lattice structures, offering guidance for their implementation. |
